What Is Avascular Necrosis?
The destruction of bone tissue as a result of a lack of blood supply is known as avascular necrosis (AVN). It may also be referred to as ischemic bone necrosis, aseptic necrosis, or osteonecrosis.
If AVN is not treated, the bone may collapse. Your hip is where AVN typically manifests. The shoulder, knees, and ankles are further potential locations.
Symptoms of Avascular Necrosis
AVN typically has no symptoms in the early stages. Pain increases as the illness worsens. At initially, pressing on the damaged bone can be the only thing that hurts. The pain could then become ongoing. You can have excruciating pain that prevents you from moving your joint if the bone and surrounding joint collapse. Separating the onset of symptoms and bone collapse, there might be several months to more than a year between them.
